Microstructural Study of 17-4PH Stainless Steel after Plasma-Transferred Arc Welding. [PDF]
Materials (Basel), 2015 The improvement of the surface qualities and surface hardening of precipitation hardened martensitic stainless steel 17-4PH was achieved by the plasma-transferred arc welding (PTAW) process deposited with Co-based alloy. The microstructure of the heat affected zone (HAZ) and base metal were characterized by optical microscope (OM), scanning electron ...
